Discharge condensation water collection system for collaborative removal of pollutants

Abstract

The invention relates to a system for removing pollutants while discharging, condensing and collecting water. The system comprises a shell, wherein a pre-charged subsystem, a condensing heat exchangesubsystem and a multifunctional subsystem which are communicated with one another are arranged in sequence in the shell in a flue gas charging direction; the pre-charged subsystem comprises a first-level tank; a first discharge electrode wire is arranged in the first-level tank; the condensing heat exchange subsystem comprises a second-level tank; a first heat exchange tube bundle is arranged in the second-level tank; the multifunctional subsystem comprises a third-level tank; a second discharge electrode wire and a second heat exchange tube bundle are arranged in the third-level tank. By adopting the system, a pre-charged technology, a discharging, condensing, heat exchange, coupling, strengthen steam condensation efficient water collection technology and a pollutant synergetic removal technology are adopted, so that the condensing heat exchange effect of flue gas is enhanced, the water collection efficiency is increased, and fine particles, residual liquid drops, condensable particles and soluble salts in the flue gas can be captured in order to realize effecient and synergistic removal of pollutant components in the flue gas.

Description

technical field [0001] The invention belongs to the technical field of flue gas treatment in the energy and electric power industry, and in particular relates to a system for collaborative removal of pollutants through discharge condensation and water collection. Background technique [0002] Thermal power generation is still the main source of electricity in my country at present, saving water and reducing water consumption indicators is an inevitable choice and development trend for the development of my country's electric power industry. [0003] Water vapor in the flue gas at the outlet of the wet desulfurization system in thermal power plants accounts for 12% to 18%. The flue gas not only contains soluble salts, acid gases and other pollutants, but also a large amount of water vapor will carry latent heat, which reduces the efficiency of the boiler. Chimney discharge will cause huge waste of water resources. It is particularly strong in the Midwest, especially in water...
